	State *StateDB
}

type StateDB

type StateDB struct {
	// contains filtered or unexported fields

func (*StateDBManage) StorageTrie

func (shard *StateDBManage) StorageTrie(cointyp string, addr common.Address) Trie

StorageTrie returns the storage trie of an account. The return value is a copy and is nil for non-existent accounts.

func (*StateDBManage) SubBalance

func (shard *StateDBManage) SubBalance(cointyp string, accountType uint32, addr common.Address, amount *big.Int)

SubBalance subtracts amount from the account associated with addr.

func (*StateDBManage) Suicide

func (shard *StateDBManage) Suicide(cointyp string, addr common.Address) bool

Suicide marks the given account as suicided. This clears the account balance.

The account's state object is still available until the state is committed, getStateObject will return a non-nil account after Suicide.

func (*StateDBManage) UpdateTxForBtree

func (shard *StateDBManage) UpdateTxForBtree(key uint32)

func (*StateDBManage) UpdateTxForBtreeBytime

func (shard *StateDBManage) UpdateTxForBtreeBytime(key uint32)

type Trie

type Trie interface {
	TryGet(key []byte) ([]byte, error)
	TryUpdate(key, value []byte) error
	TryDelete(key []byte) error
	Commit(onleaf trie.LeafCallback) (common.Hash, error)
	Hash() common.Hash
	NodeIterator(startKey []byte) trie.NodeIterator
	GetKey([]byte) []byte // TODO(fjl): remove this when SecureTrie is removed
	Prove(key []byte, fromLevel uint, proofDb mandb.Putter) error
}

Trie is a Matrix Merkle Trie.
